In the form of the invention shown in Figure 2, the construction is substantially the same insofar as wheel spider and lug are concerned, and corresponding reference numerals have been applied thereto. However, in this form of the invention, the rim is of slightly different construction, embodying the first rim member 6 corresponding to the rim member 6 of Figure 1, but the bead flange member I in this form of the invention does not have the flange I3' extend radially inwardly of the flange 9, but it extends the same distance to provide the same inner annular peripheral surface as is provided 4by theV flange 9. In this rim construction, a separate ring 35 is provided, which ring has the internal axia1 flange '36 engaging the inner axial surface of the flanges I3 and 9. This ring 35 abuts against the outer radial face of the flange I3', and the flange portions are rigidly clamped together by means of the studs 31, which receive the nuts 38, securing these parts rigidly together. The ring 35 is provided with the radially and axially outwardly extending seat 39 formed on the undersurface of an annular projection 40 rolled integrally therewith, the boss being interrupted to accommodate the studs 31. The seat 39 is adapted to be engaged by the corresponding surface I1 of the lugs I8 for clamping the rim in position.

It will be apparent that with this construction the rim is mounted upon the spokeend in the same manner as heretofore described, and the operation of the lug is the same in insuring that the rim will be rigidly chorded into position on v first rim portion having a bead flange at one edge' and a radially inturned flange at'the other edge, means including a second annular bead flange member having a flange portion abutting against said inturned flange and rigidly secured thereto, and circumferentially spaced outwardly projecting portions on said member having tapered mounting seats on the radial inner surface thereof.

2. In combination, a rim including an axially projecting boss having the radial inner surface thereof tapered upwardly and outwardly, a wheel spider having radially extending spokes provided with axially projecting U-shaped sockets terminating in parallel axially extending seats, a rim mounting lug having wing portions supported on said seats and having an arcuate tapered radially outwardly disposed surface, means for drawing said lugs axially inwardly onsaid seats to wedge said boss outwardly for chording said rim into position on said spoke ends.

3. In combination, a type rim having a circurnferential boss on the outboard surface of said rim provided with a radially and axially outwardly extending mounting seat, a wheel spider having radially extending spokes terminating in a radial shoulder radial inwardly extending flange means on said rim adapted toaxially abut said shoulder for limiting axial inward movement of said rim over said spoke ends, and clamping lugs carried by said spoke ends and movable 81X- ially thereon to engage said mounting seat for clamping said rim flange means against said shoulder and for chording said rim intermediate said spokes.

4. In combination, a split rim having a rst annular rim portion comprising an annular bead flange at one edge and a radially inwardly directed flange at the other edge, a second rim portion comprising an annular bead flange portion having an axially extending flange overlying said other edge of said first rim portion,

a radially inwardly directed flange axially abutting the corresponding flange of said first rim portion, and an annular outwardly projecting boss provided with a radially and axially outwardly tapered mounting surface, said boss being interrupted at circumferentially spaced points, and a series of bolts extending axially through said abutting flanges at said points to clamp said rim portions together.

5. The combination of claim 4 wherein said second rim portion has its radially inwardly extending flange provided at its inner periphery with an axially directed annular lip forming a seat for the flange of the first rim portion.

6. In a rim structure, a first annular rim member having a bead flange at one lateral edge thereof and having a radially inturned flange at the opposite edge thereof, a second rim member comprising a bead flange portion, an annular axially extending portion overlying the rim portion of said first rim member, and a radially inwardly extending flange portion abutting axially against the inwardly directed flange of said first rim member, an annular ring having a radial portion abutting against the outside 4face of said radially inwardly directed flange of said second rim portion and an axially directed lip forming an annular seat for said flanges of said rim portions, and an annular projection on the outboard face of said ring vproviding a tapered rim mounting seat.

7. In a rim struture, a pair of telescopically arranged rim portions each having a bead flange and forming a channel shaped rim, each portion having a radially inwardly extending flange, said flanges being in axial abutment when said rim portions are arranged in operative position, an annular ring having a radial portion abutting against the outboard ange and having an annular axial lip portion extending Within the inner annular periphery of said flanges, an annular pro- Ijection on the outboard face of said ring having `tapered inner annular surface, a wheel spider rim has radially inwardly directed flange means adapted to engage said abutment means on said spoke end.

1i. In combination, a channel-shaped tire rim having a radially inwardly directed flange adja- -cent one edge thereof, an annular projection disposed on the outboard face of said rim axially outwardly of said flange and having a. radially' and axially outwardly tapered inner annular sur-
